There is a zip file which contains 1 folder called PURE. In this folder are three sub folders: Complexes Ligands Polymer In the "Complexes" folder are 5 sub-folders which are labelled as according to the label for the complexes in the paper. In each sub-folder are the raw NMR data in folders by the experiment type. In the "Ligands" folder are 3 sub-folders which are labelled as according to the label for the ligands in the paper. In each sub-folder are the raw NMR data in folders by the experiment type. In the "Polymer" folder are 3 sub-folders. Kinetics - this contains the analysis of the NMRs for the kinetic runs labelled with a time. Sub folders table 2 and 3 give the raw data for the polymerisation tables 2/3 in the main paper. There are also three files (DSC, kinetics, MALDI) which give our processed results.
